Be it known that I, JOSEPH BiJUn, a citizen of the United States, and a resident of the boron h of Manhattan, city, county, and State of ew York, have invented an Improvement in Electrical Apparatus for Internal-Com-bustion Engines, of which the following is a specification.

This invention relates to electrical apparatus for internal combustion engines. ne of the objects thereof'is to provide apparatus of the-above type of simple construction in which the parts are compactly disposed and securely held'in position. Another object is to provide apparatus of the above type in which the parts may be readily and conveniently assembled in exact position i for most effective action. Another object is to provide for starting motors a practical and inexpensive mounting of few parts and efficient action. Other objects Wlll be in and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts wh ch will be exemplified 1n the structure hereinafter described and the scope of the application of which will beindicated in the following claims..-

In the accompanying drawings 1n which is shown one of .various possible embodiments of this invention,

Figure 1 is a diagrammatic side elevation, certain parts being cut away in order to show the construction more clearly.

Fig. 2 is a detail end view of a portion of the parts shown in Fig. 1. I

Fig. 3 is a sectional elevation taken substantially on the line AA of Fig.. 2;

Similar reference characters refer to similar parts throughout the several views of the drawings. l

Referring now to Fig. 1 'ofthe drawings, there is shown at' 1 an internal combustion engine comprising a fly wheel 2, and it may be noted that this en ine is preferably of the automobile type; referably formed integral with the engine,cas1ng 3 is a caslng .4 extending about the fly wheel and pro- Vided with the flange 5 by which it may be connected with a similar casing to lnclose 1 the parts, the latter casing not being here shown as it forms in itself no part of the present invention.

7 ;.on the squared armature shaft 8 of an electrlc motor 9. Although. this dynamo 1s here shown as a motor, it is to be understood that many .of the features of this invention are applicable to-the mounting'of a dynamo of the generator form.

The pinion 7 is provided with a grooved collar 10 in which fits a fork 11 upon the shifting rod 12 which is. connected by the pivoted link 13 with the lower end of a bell crank lever 14. This lever is forked about the link rod 13 between a fixed collar 15 and a yielding collar 16.held in position by the spring 17 and nut 18. Lever 14 is provided with a fixed pivot 19 from which it extends upwardlyto the foot pedal 20 by which it 1s actuated from the seat of the motor car, and it is normally retracted into theposition shown by the spring 21 connected between its lower end and a fixed part of the vehicle 22. Connected to the lever 14 at the pivot .23 is an actuating rod 24 of a switch box 25.

This rod bears the suitably insulated contact26. adapted when moved in the directlon indlcated by the'arrow to bridge the .contacts 27 and complete the circuit of the the latter. s

The motor 9, as-best shown in Fig. 3 of the drawings, comprises an outer shell or casing 28 which fits within the annular flange or socket 29 upon a supporting member 30 and is retained in' position therein partially by I means of the longitudinal screws 31 and partially by the radial screws 32. Screws 31 pass through the body of the .rnember 30 and screws 32 through its flange 29. It will be seen from this construction that the member 30 not only actsas a sup,- port for the motor, but also as one of the heads of the 'motor casing havin therein the bearing 33 for the motor'sha 8 upon which the pinion 7 is mounted to slide. The

member 30 is provided with the outwardly extending wings 34:, as best shown 1n Fig. 2 of the drawings, and each of these is provided with an opening through which a bolt 35 secures it to the casing 4, these bolts being three in number.

There is formed in the casing 4: a circular opening 40 precisely concentric to the .desired position of the motor shaft of larger diameter than the pinion 7 and upon the surface of the fitting 30 toward the fiy wheel there is a projecting boss 36 accurately turned concentric with the axis of the motor shaft and adapted to fit closely the opening in the casing 4 except at the points where the registering recesses 37 permit access to the screws 31.

By this arrangement, the member 30 is interlocked with the casing in precisely the desired position for proper and efiicient meshing between the pinion 7 and the gear 6, and the outwardly extending wings 34 together with the socket 29 provide so rigid and secure a mounting for the motor that additional support is unnecessary and the end thereof away from the fly wheel may be left free.

In the use of the above apparatus, the parts are assembled by first securing the fitting 30 about the end of the motor as by the screws 31 and 32, and the pinion 7 is mountedupon the extended shaft 8. The opening in the casing being exactly the same in position and size for a given type of motor is positioned to receive the boss 36 without fitting or adjustment. the extended shaft and the pinion 7 readily passing through the opening 40, and the bolts or heavy screws 35 are thereupon driven into position. The actuating linkage then being connected, the parts are in condition for use by the manipulation of the foot pedal hereinbefore described. The pinion is thrown into mesh with the fly wheel to turn over and start the engine or is thrown out of mesh upon the release of the pedal as the parts are drawn back by the spring 21.

It is to be understood that the linkage is merely illustratively shown and that other means may be employed for power transmission. he specific form of linkage shown is fully described and claimed in the copendin application of Lionel M. VVolifsohn, erial No. 153.359 filed March 8th, 1917. The invention herein claimed is substantially independent of the manner and means for transmitting power between the dynamo and the engine.

It will thus be seen that there is provided simple and compact and yet thoroughly ef fective and reliable apparatus in which the several objects of this invention are achieved.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limitin sense.
